The first book entirely devoted to this topic, Ecosystem Engineers begins with the history of the concept, presenting opposing definitions of ecosystem engineeing. These varied definitions advance the debate and move past trivial difficulties to crystallize key issues such as the value of process-based vs. outcome-based. Authors include case studies spanning a wide spectrum of species and habitats, including above and below-ground, aquatic and terrestrial, and extant and paleontological examples. These studies enable readers to understand how the categorization of species as ecosystem engineers allows scientists to forge new explanatory generalizations. Key for all ecologists and environmentalists, this book ultimately illustrates how to inform and manage natural resources.
* The only consolidated treatment available
* Provides definitions, case studies, and examples of ecological models
* Discusses how ecosystem engineering can inform and improve the management of natural resources
* Includes contributions from Clive Jones, the leading figure in the development of the ecosystem engineer concept, and many other eminent ecologists, such as Alan Hastings

As our world becomes increasingly urbanized, an understanding of the context, mechanisms, and consequences of city and suburban environments becomes more critical. Without a sense of what open spaces such as parks and gardens contribute, it's difficult to argue for their creation and maintenance: in the face of schools needing resources, roads and sewers needing maintenance, and people suffering at the hands of others, why should cities and counties spend scarce dollars planting trees and preserving parks? In "Constructed Climates," ecologist William G. Wilson demonstrates the value of urban green. Focusing specifically on the role of vegetation and trees, Wilson shows the costs and benefits reaped from urban open spaces, from cooler temperatures to better quality ground water--and why it all matters. While "Constructed Climates "is a work of science, it does not ignore the social component. Wilson looks at low-income areas that have poor vegetation, and shows how enhancing these areas through the planting of community gardens and trees can alleviate social ills. This book will be essential reading for environmentalists and anyone making decisions for the nature and well-being of our cities and citizens.
